Help needed creating new user on remote machine

dexterit · 2019-02-08T16:15:53.000Z

Hey all,

I have been going nuts trying to figure this out. I am trying to put together a script to create a local user account on a remote machine (a server) and set properties on the account. In my testing, I have managed to get an account created LOCALLY but when pointing to the remote computer, it doesnt work

I am a novice to powershell so the script below may not look very efficient in the use of commands/variables but it works (locally). Essentially, the username and the password is to be the mac address of the wifi adapter - the full name is to be the laptop model and the description its asset tag barcode # - the first 6 lines defines the barcode# and model

$computername = $env:computername
$newcontent = $computername.replace(($computername.substring(0,3)),"0000") 
$barcode= $newcontent -replace ".{4}$"

$model = wmic csproduct get name
$model2 = $model -replace'.*?(?=.{1,7}$)'
$model3 = $model2 -replace "\s+", ""

$mac = get-wmiobject win32_networkadapter | Where-Object {$_.Name -match "wireless"} | Select-Object MACAddress -unique | foreach {$_.MacAddress -replace ":",""} 
$mac = $mac.tolower()
$UserName="$mac"
$Password="password123"
$Computer = [ADSI]"WinNT://$Env:the_computer_name" 

net user $UserName $Password /add /active:yes /comment:$barcode /fullname:$model3
wmic useraccount where "name='$UserName'" set PasswordExpires=false
wmic useraccount where "name='$UserName'" set PasswordChangeable=false
net localgroup testgroup $mac /add

If you post code, please use the ‘Insert Code’ button. Please and thank you!

PLEASE READ BEFORE POSTING! Read if you're new to the PowerShell forum! Programming & Development

Hi, and welcome to the PowerShell forum! Don’t apologize for being a “noob” or “newbie” or “n00b.” There’s just no need – nobody will think you’re stupid, and the forums are all about asking questions. Just ask! Use a descriptive subject. Don't say "Need help" or "PowerShell Help", actually summarize what the problem is. It helps the rest of us keep track of which problem is which. Don’t post massive scripts. We’re all volunteers and we don’t have time to read all that, nor will we copy, past…

Have you just tried to invoke it?

invoke-command -computername $RemoteComputerName -Scriptblock {
    #YourCodeHere
}

In addition to using Invoke-Command, as Neally suggested, have you tried using New-LocalUser instead of WMIC?

Use single quotation only when you do not need any value, you say remote computer, but why $env:computername?

$computername = $env:computername   # place computername here for remote access
$username = 'useranme'
$password = 'P@ssw0rd1'
$desc = 'Local admin account'
$computer = [ADSI]"WinNT://$computername,computer"
$user = $computer.Create("user", $username)
$user.SetPassword($password)
$user.Setinfo()
$user.description = $desc
$user.setinfo()
$user.UserFlags = 65536 ## password never expires
$user.SetInfo()
$group = [ADSI]("WinNT://$computername/administrators,group")
$group.add("WinNT://$username,user")

^ change value accordingly
